REFINING-MACHINE.

To all whom it may concern:

Be it known that l, Jonx C. linmnxo, a citizen of the United States, at presentre siding in Vashington, in the District of Columbia, have invented a new and useful Improvement improvement upon the machine shown and described in my. application for patent tiled July 2, 1008, and bearing b'erial Number 4+t1,729.

The machine is also specially adapted for themixing of both liquid and gaseous purifying ingredients with oils or other mate-- rials and the machine is also particularly fitted for the separation of the butter-fats from milk'or creari.

Another object of the invention is to produce a 'machine whereby sugar and sugarsyrups can be purified and bleached in the absence ot chareoah and the machine can also be used for the-refining of mineral oils without danger to the operator.

The above objects are 0 tained by constructing a machine in which by means of the mechanism hereinafter described a liquid of any kind Will be thorbughly broken up, and where a second liquid or other form of purifying agent is added, the same will be thoroughly mixed and incorporated with the liquid intended to be purified or refined.

\Vith these various objects in vieug my invention consists essentially in the employment of a receptacle within which is arranged a series of rotary 'dashers for causing the material to be rapidly forced from one end of the machine to the other, arranging a stationary screen adjacent each rotary dasher and through. which the material is forced. and thereby separated into small particles, a rotary screen being arranged adjacent and behind each stationary screen, said rotary screens being double and adapted to not only carry on the separation and breaking up of the particles but also aiding materially in carrying around the ingredientsand delivering them in a finely divided state to the .next rotary dasher, which operating in the same manner as the first mentioned dasher performs itstunction upon the Specification of Letters Patent.

finely divided material and passes it on to the next set of screens and dashers to the end of the machine;

.The invention also consists in arranging a rotary dasher at the extreme end oi? the machine, the blades thereof being inclined reverse to the blades of the other dashers whereby the movement of the material is arrested at the end of the machine, thereby permitting its discharge in 'a free and easy manner.

The invention consists also in providing a novel form of support together with the. novel mains of covering the-receptacle and at the same time securing the stationary screens in place.

The inventio nconsists also in various novel features otconstruction and also in the combination or arrangement of these various parts, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this v specificationz+higure 1 is a vertical longitudinal sectional view of the finachine, the dashers being shown in elevation. Fig. 2 is a horizontal sectional view, thedashers Fig. is a trans verse sectional view-on the line 3- 3 of Fig. 1. Fig. 4 is a sectional elevation of one of the rotary screens, and Fig. 5 is a side elevation of one of the stationary screens.

In the p acti 'al embodiment of my invention I employ an essentially .5 -shaped trough, or receptacle consisting of the curved sheet metal plate A having otlsets as shown at A and flanged along the upper edges as shown at- A. The ends B are U- shaped of course, and are riveted to curved angled bars B and B and the bottom 0t the receptacle A is also riveted to the angled iron B. and the ttCliGt ffi is riveted to the angled iron B and all of these parts connected as described rest in the curved angled iron support constituting a portion. of the end support- C, this end support being pret} erably made of cast-iron, and providing the legs for supporting the machine at each end.

A bracket arm C extends upwardly from the central portion of the end-support and carries a bearing block C in which is journaled the projecting end ofithe shaft D, it being understood that there is a bearing at each end, and that. the shaft passes centially through fihe'receptacle, and is upper-ted each end inxthe bearings (3 and at one en is provided with. a power-pulley D and at the opposite end with a balance-wheel D i From the foregoing description it will be noted that I provide a U-shaped receptacle closed at each end and also supported at each end, and furthermore it will be noted. that thereceptacle is jacketed upon the bottom and. that the ends of the jacket and receptaare securely connected in an exceedingly strong and durable manner.

As before stated the horizontal shaft D sses longitudinally: through the receptacle,

3: I is said receptacle being intended to receive the oil or other material to be purified and refined, and for the purpose of quickly and thoroughly breaking up the material into .hne particles or atoms and at the same time thoroughly commingling any liquids or es-which may be added for purifying and ring purposes, I arrange upon the rotary It a series of rotary dashers, for the pure of causing the material to be rapidly d from one end of the machine to the 3, and in connection with each rotary I employ a stationary and also ry screen, said screens being soconand arranged as will more fully apthat the material in being forced from end to the other will be thoroughly sepal, broken up,atomiaed and commingled. material is fedthrou'gh an opening A adjacent the end of the machine 1. are a rotary dasher E which immediately s the material to a rotary dasher F, b is the first rotary the entire which extends oughout the ma- "and in the present instance employ a such dashers in the series. Adjacent rotary dasher F and behind the same is l .ationary screen G, and adjacent each staonary screen and behind the same is a rory screen H, the dasl ers and rotary screens ng keyed u on the shaft, said shaft being grooved longltudinally, and in practice I prefer-to arrange spacing collars between all the dashers and screens so that by tightening up the end nuts D all of the movable parts can be securely looked upon the shaft, and it will be understood that the dashers and ro- -yscreens areal-ranged upon the shalt be- )re the end plates of the receptacle are fastened on. The material is discharged ough an opening A and it will be noted t the last rotary screen is adjacent one do of this discharge opening, and adjacent opposite side of d discharge opening id mounted upon the rotary shaft is arod dasher E, similar in. all respects to the rotary dasher E, except that its blades are inclined reverse to the inclination of the blades of-the dasher E, and the function of this end daslier E is to throw back the ma' terial from theextreme end of the machine,

ceases thereby arresting the movement of the-material directly over the opening A and consequently materially aiding in the free and easy discharge of the material from the mabottom, as shown at-G for the purpose of preventing any possible escape of the material along the bottom of the receptacle, without being first subjected to the actions of the rotary dashers and screens, and for the purpose of holding the lower sections of the stationary screens in place, I employ curved angled irons G* which are secured at regular intervals to the bottom of the receptacle and extend upwardly as far as the oltsets A The upper sections G of the rotary screen consist of wire gauze-held between theauctal fran'ie-work, and it will be noted that this metal frame work is shouldered as shown at and the shoulders rest upon the offsets or shoulders A, and at the center of eachi'ot ary screen it is providedwith a half-collar which embraces the rotary shaft,

For the purpose of providing a curved upper side to the receptacle, and at the same time securing the upper section of the rotary screens in place, I employ a series of curved plates 1, each plate being of a length and curved in such a manner as to extend from side to side of the machine, and just leave clearance enough for the rotation of the rotary dashers and screens, and. each curved plate I has a horizontal flange or footpiece I, which rests upon the ofiset or shoulder A, and furthermore, each plate is constructed with a vertical flange 1 and when these plates are arranged from end to end, each upper sect-ion of the rotary screen will be between the flanges of two adjacent platesections, and by means of rivets, all of the sections and screens can be securely fastened together: A fiat top plate K extends over the entire machine, and is riveted or bolted to the side flanges and end flanges 'of'the receptacle. it will of course be understood that openings are produced in this top-plate v for the feed-tubes previously referred to.

The acketis provided with an inlet pipe L and a discharge pipe L by means of which anysuitablc heating'or cooling medium may be introduced into and circulated through the jacket for the purpose of heating or cooling the contents of the receptacle, and the manner of connecting the jacket to the; sides andendsof the receptacle renders it steam-- ee aae tight so thatsteam; may be employed as a 'heatlng medium Whenever desired. A plurality of drainpipes M extend. from the {bottom ofthe receptacle through the acket and each is provided with a cock M, and it will noted that these drain-pipes are arranged between each pair of angled irons against which the stationary screens bear,

and by means of these drain-pipes I am en abled to quickly and thoroughly remove any and all sediment or material which might remain in the bottom of the receptacle.

Each rotary screen H as heretofore described is arranged adjacent to and to the rear of, the stationary screen, and the material is rapidly forced through the stationary screen and is partially separated, broken up or atomized by its assage through this stationary screen, but liy having a rotary screen immediately behind the stationary screen and rotating in unison with the rotary double screen as shown there bein two disks of wire gauze I-I' connected-to two concentric circular rings H and between the said wire gauze disk and concentric rings are the lozenge-shaped spacing blocks H and it will be noted that the outer series of blocks are arranged with their angular edges coincident with the end of the screen, and this outer series of blocks just clear the bottom of the receptacle, so as to take up by a scraping action the material in the bottom of the receptacle, and by having the rotary screens double, and also by utilizing the peculiar shaped spacing blocks, the operation of separation 0r atomizing is much more easily accomplished.

In operation the material to be refined or purified, is introduced into the machine through the feed-tube and with it any desired form of purifying or refining agent, either in the solid or liquid form, and the moment the material enters the machine the first rotary dasher E will immediately start it toward the opposite end of the machine and here it comes into. contact with the first of the series of rotary dashers F, and the rotary dasher rapidly whirls it around and forces it through the first stationary screen, "and after passing through the stationary screen it is caught up. and carried around and passed through the first rotary screen, and is then passed on to the next rotary. dasher and all of'these operations are again repeated as often'as desired, and in the meantime any suitable gaseous re-agentcan be introduced through the gas supply pipe, if desired.

The material by being continually subjected to the churning and screening operations is broken up into the finest particles and every particle of the material to be purified is brought into intimate contact with every particle of the purifying and refining agents, and in this manner, the complete operation is carried on so that when the material emerges from the machine the purified and refined product can be immediately collected. For the purpose of removing the pressure from the rear end of the machine I have provided a supplemental dashcr which checks the motion of the material at the end, and facilitates its free and easy discharge through the discharge tube or chute. By having these rotary dashers at the opposite ends of the machine Iain able to do away with stul'ling boxes and consequently only employ split sleeves for surrounding the shaft at each end between the ends of the receptacle and the bearings for the shaft.

The advantages of the special features of construction having been fully pointed out during the detailed descrip n of the various parts, it is not necessary to further enumerate them.

It will thus be seen that I provide an exceedingly cheap, simple and highly ellicient machine for refining oils, and similar materials, and capable of carrying out all of the objects of the invention hereinbefore referred to.

If'desired strips of wire screen may be employed between the two rotary screens in place of the bars. and at times both the bars and strips of screens may be employed.

One decided advantage of this machine is that the milk passed therethrough will evaporate at a low temperature preserving its FOOCl-VfillllQ.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a machine of the kind described, the

combination with a receptacle, of a rotary dasher, a stationary screen adjacent the said dasher, and a rotary screen adjacent the stationary screen.
